Abstract/ Executive Summary:

An experiment was conducted at Crop Botany Department of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh to study flowering behaviour and flower morphology of passion fruit grown from cutting and grown from seed. Flowers opened within 10:52 to 12:25 hr. in plants grown from cuttings and within 10:55 to 12:31 hr. in seeded plants. From visible flower bud to full bloom requires 14.17 days for plants grown from cutting and requires 13.33 days for plants grown from seeds. Flowering started earlier in case of plants grown from cutting which continued 152 days as against 99 days in case of plant grown seed. Average size of floral parts was recorded more or less similar in both types of plants. Percentage of fruit set was higher under hand pollination than under natural pollination.

Location: Crop Botany Department of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur

Start Date: 00-00-2002

End Date: 00-00-2003

Program Area: Crop-Soil-Water Management

Commodity: Fruit

Objectives:

To study flowering behavior and flower morphology of passion fruit grown from cutting and grown from seed

Methodology:

The experiment was carried out during 2002-2003 at the experimental farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur. Two types of plant materials were used e.g., (i) Plant grown from seeds, (ii) Plant grown from cutting. Land preparation, manuring & fertilization and retransplanting were done accordingly. Days to appearance of flower bud, first flowering node number, days to first flowering, floral morphology, time of anthesis and fruit set percentage were recorded.

Achievement/Findings:

It may be concluded from the above study that, flowers opened within 10:52 to 12:25 hr. in plants grown from cutting and within 10:55 to 12:31 hr. in plants grown from seed. Flowering started earlier in case of plants grown from cutting which continued 152 days as against 99 days in case of plant grown from seed. Average size of all floral parts was recorded more or less similar in both types of plants.
